2007 Nutrient Management Protocol for Ontario Regulation 267/03 Made under the Nutrient Management Act, 2002

Part 3 - Nutrient Units: How Farmers Determine Whether Their Farm Units are Subject to the Regulation

Table of Contents

  1. Table 3.1 - Livestock Information: Type, Nutrient Amount. Nutrient Unit and Housing Capacity

Using the nutrient units ("NU") concept helps ensure an 'apples to apples' comparison between sizes and types of farm units. Land application requirements for a farm unit, are based on the specific farm unit's NMP, not NUs. NUs are not the same as livestock units, which are used in regimes other than the Nutrient Management Act, 2002, S.O. 2002, and which have been used for the purpose of calculating Minimum Distance Separation setbacks in the previous version of that document.

3.1 Using Nutrient Units to Determine the Obligations of Agricultural Operations Carried Out at a Farm Unit

For agricultural operations with farm animals it is necessary to determine the number of NUs managed on a farm unit. The number of NUs generated on a farm unit by a particular type of farm animal is calculated by dividing the number of farm animals by the number given in the Nutrient Units Column shown on Table 3.1 Livestock Information: Type, Nutrient Amount, Nutrient Unit and Housing Capacity. If the farm unit has more than one type of farm animal present on it then this calculation would have to be completed for each type of animal separately, then all the results totaled to give the total NU generated by farm animals on the farm.

Notes: * DM = dry matter

  1. Average weight rounded to 3 significant digits
  2. Manure production numbers rounded to 4 decimal places
  3. Blank manure production and dry matter entries indicate a non-typical housing process
  4. Livestock housing capacity is rounded to 2 decimal places if above 0.2 m2/animal and 3 decimal places if below 0.2 m2/animal
  5. Blank livestock housing capacity values indicate that information is not available
  6. Livestock density is based on barn area only for a housing system (outdoor yard is not included)
  7. Livestock housing capacity numbers are used to develop an estimated barn size
